I would say at a glance that is a wooden pattress that had four round 'toggle' switches mounted on it. And yes, wooden trunking - which was also run under floorboards as well as on walls.
Second that. It's difficult to see anything for scale, but the overall layout of what appear to be old screw holes in relation to the holes where wires would have been brought through to the switches are about right.
Only thing I notice is that assuming I'm right about what appear to be screwholes just below and outboard of the wire holes, the switches were likely all mounted upside down.
The majority of tumbler switches such as the Crabtree and Britmac types above had the terminals below the tumbler mechanism because of the way the latter operated (except in the case of 2-way switches which normally had the extra terminal above).
Were there any makes which had the terminals above the tumbler mechanism?
P.S. Actually, thinking about it some more, it may be that the pattress was used with older types of tumbler switch than the 1930's - 1950's types I have mind, or possibly that this pre-dates the adoption of the "up is off" convention in Britain.
